摘要

本文设计了一种用于5G通信系统的40nm CMOS工艺的39ghz功率放大器(PA)。采用深ab类差分共源放大器拓扑结构，结合感应源退化和优化的功率组合技术，进一步提高了放大器的输出功率和功率效率。在39 GHz时，两级放大器的峰值功率附加效率(PAEmax)为31.8%，饱和输出功率(Psat)为21.6 dBm，功率增益为23.5 dB。

A 39 GHz Power Amplifier with High Output Power and High Efficiency for 5G Communication System

In this paper, a 39 GHz power amplifier (PA) is designed in 40-nm CMOS process for 5G communication system. By means of a deep class-AB differential common source PA topology, with the inductive source degeneration and optimized power combining techniques, the output power and power efficiency of the proposed PA are further improved. At 39 GHz, the two stage PA achieves peak power-added efficiency (PAEmax) of 31.8%, saturated output power (Psat) of 21.6 dBm, and power gain of 23.5 dB.
